Hi,
After another episode of disappearance, here is an updated iteration of the
tunables patch with suggestions from Florian, Carlos and H. J. incorporated.
Changes since the last version:
- Fixed mallopt behaviour using a set of intermediate functions that the
callback and __libc_mallopt use. I did not make them into direct callbacks
because the callbacks are built only when tunables is enabled.
- Loads of comment and documentation fixes based on Carlos' and Florian's
suggestions
- Call __init_tunables even earlier to ensure that tunables are initialized
before get_cpu_features is called.
